Answer:

It is correct. Alan can tell by looking at the graph that all sides are congruent.

Step-by-step explanation:

The length of a side can be found from the Pythagorean theorem. The square of a side length of the figure is the sum of the squares of the sides of the right triangle of which the figure's side is a hypotenuse. In each case, those right triangles have side lengths of 1 and 4, so the figure has side lengths that are ...

√(1² + 4²) = √17

All the figure's sides have this geometry, so they are all √17 in length. The fact that all sides are congruent is what makes the figure a rhombus. (The fact that sides are parallel is additional confirmation.)

Eggplant has a yield of 81%. If you purchase 12lb of eggplant, how many pounds will you be able to use?(round to the nearest hun

Aleonysh [2.5K]

Answer:

9.72 lb

Step-by-step explanation:

Yield = the amount or quantity produced or returned.

Given:

Yield of eggplant = 81%
Amount of eggplant purchased = 12 lb

To determine how many pounds of eggplant you will be able to use, calculate 81% of the amount of eggplant purchased.

$\begin{aligned}\sf 81\% \: of \: 12 \: lb & = \sf \dfrac{81}{100} \cdot 12\\\\& = \sf \dfrac{81 \cdot 12}{100}\\\\& = \sf \dfrac{972}{100}\\\\& = \sf 9.72\:lb\end{aligned}$

Therefore, you will be able to use 9.72 lb (nearest hundredth).
